------------------

From: Kai-Heng Feng <kai.heng.feng@canonical.com>

commit de3af5bf259d7a0bfaac70441c8568ab5998d80c upstream.

Corsair Strafe RGB keyboard has trouble to initialize:

[ 1.679455] usb 3-6: new full-speed USB device number 4 using xhci_hcd
[ 6.871136] usb 3-6: unable to read config index 0 descriptor/all
[ 6.871138] usb 3-6: can't read configurations, error -110
[ 6.991019] usb 3-6: new full-speed USB device number 5 using xhci_hcd
[ 12.246642] usb 3-6: unable to read config index 0 descriptor/all
[ 12.246644] usb 3-6: can't read configurations, error -110
[ 12.366555] usb 3-6: new full-speed USB device number 6 using xhci_hcd
[ 17.622145] usb 3-6: unable to read config index 0 descriptor/all
[ 17.622147] usb 3-6: can't read configurations, error -110
[ 17.742093] usb 3-6: new full-speed USB device number 7 using xhci_hcd
[ 22.997715] usb 3-6: unable to read config index 0 descriptor/all
[ 22.997716] usb 3-6: can't read configurations, error -110

Although it may work after several times unpluging/pluging:

[ 68.195240] usb 3-6: new full-speed USB device number 11 using xhci_hcd
[ 68.337459] usb 3-6: New USB device found, idVendor=1b1c, idProduct=1b20
[ 68.337463] usb 3-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 68.337466] usb 3-6: Product: Corsair STRAFE RGB Gaming Keyboard
[ 68.337468] usb 3-6: Manufacturer: Corsair
[ 68.337470] usb 3-6: SerialNumber: 0F013021AEB8046755A93ED3F5001941

Tried three quirks: USB_QUIRK_DELAY_INIT, USB_QUIRK_NO_LPM and
USB_QUIRK_DEVICE_QUALIFIER, user confirmed that USB_QUIRK_DELAY_INIT alone
can workaround this issue. Hence add the quirk for Corsair Strafe RGB.
